RESUMEN
BACKGROUND: Evidence regarding the effect of body mass index (BMI) on complications following anatomic shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (rTSA) remains controversial. This high-powered study examines the effect of BMI on surgical and medical complications following aTSA and rTSA. METHODS: This retrospective cohort study was conducted using the Premier Healthcare Database to query all adult patients who underwent primary, elective TSA (aTSA, rTSA) from 2016 to 2020. Patients eligible for inclusion were identified using International Classification of Diseases -10 and CPT codes for primary TSA. Patients were stratified into 3 subgroups based on BMI (BMI <30 kg/m2, BMI 30-35 kg/m2, BMI >35 kg/m2). The primary endpoints assessed were 90-day risks of postoperative complications, revisions, and readmissions among the 3 BMI groups undergoing primary TSA. RESULTS: A total of 32,645 patients were analyzed; 10,951 patients underwent aTSA and 21,694 patients underwent rTSA. Patient populations for aTSA and rTSA differed significantly across all BMI categories in terms of age, sex, cost of care, and insurance status. After multivariate regression analysis, there was no increased risk of surgical complications in the aTSA and rTSA cohorts with BMI 30-35 kg/m2 and BMI >35 kg/m2. In the aTSA cohort, rates of acute respiratory failure (adjusted Odds Ratio [aOR] 2.65) was all significantly higher in the BMI >35 kg/m2 group. As for rTSA cohort, acute respiratory failure (aOR 1.67) and acute renal failure (aOR 1.53) were significantly higher in the BMI >35 kg/m2 group. CONCLUSION: While we found no increased risk of immediate postoperative surgical risks, patients with a BMI >35 kg/m2 demonstrated greater risk of medical complications after rTSA. Given this trend, providers should exercise caution in patient selection for TSA and counsel obese patients as to these increased risks. Future studies should aim to provide a more comprehensive picture of the effect of BMI on functional outcomes after TSA.
RESUMEN
BACKGROUND: Previous research has demonstrated that concussions increase the risk of subsequent lower extremity musculoskeletal injury in athletes. However, the risk of upper extremity injury in athletes' post-concussion is poorly understood. METHODS: All concussed football players within a National Collegiate Athletic Association (NCAA) Division I conference athletic database were identified between 2017 and 2021. After exclusions, each athlete experiencing their first concussion was then retrospectively reviewed for upper extremity injuries in the year prior to their concussion and in the year beginning at 90 days after their concussion. All upper extremity injuries were identified and the odds ratio, 95% confidence interval, and statistical significance between groups were calculated in Microsoft Excel. RESULTS: 160 de-identified football players from a single conference who were first diagnosed with concussions in the seasons from 2017 through 2021 met inclusion criteria. In these athletes the odds of upper extremity injury in year following first diagnosed concussion were 2.36 times higher than in the year prior (95% CI 1.13-4.95, p = 0.02). Shoulder was the most common site of injury with 57.7% of injuries compared to 19.2% in the hand, 15.4% in the elbow, 7.7% in the forearm, and 0% in the wrist. CONCLUSION: This study demonstrates that collegiate football players are at a 2.36 times greater risk of upper extremity injury in the year following their first diagnosed concussion compared to the year preceding it. The most common site of upper extremity injury after concussion was the shoulder. LEVEL OF EVIDENCE: III.
RESUMEN
BACKGROUND: Inflammatory arthritis (IA) represents a less common indication for anatomic and reverse total shoulder arthroplasty (TSA) than osteoarthritis (OA). The safety and efficacy of anatomic and reverse TSA in this population has not been as well studied compared to OA. We analyzed the differences in outcomes between IA and OA patients undergoing TSA. METHODS: Patients who underwent primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) from 2016-2020 were identified in the Premier Healthcare Database. Inflammatory arthritis (IA) patients were identified using International Classification of Diseases, Tenth Revision, diagnosis codes and compared to osteoarthritis controls. Patients were matched in a 1:8 fashion by age (±3 years), sex, race, and presence of pertinent comorbidities. Patient demographics, hospital factors, and patient comorbidities were compared. Multivariate regression was performed following matching to account for any residual confounding and 90-day complications were compared between the 2 cohorts. Descriptive statistics and regression analysis were employed with significance set at P < .05. RESULTS: Prior to matching, 5685 IA cases and 93,539 OA controls were identified. Patients with IA were more likely to be female, have prolonged length of stay and increased total costs (P < .0001). After matching and multivariate analysis, 4082 IA cases and 32,656 controls remained. IA patients were at increased risk of deep wound infection (OR 3.14, 95% CI 1.38-7.16, P = .006), implant loosening (OR 4.11, 95% CI 1.17-14.40, P = .027), and mechanical complications (OR 6.34, 95% CI 1.05-38.20, P = .044), as well as a decreased risk of postoperative stiffness (OR 0.36, 95% CI 0.16-0.83, P = .002). Medically, IA patients were at increased risk of PE (OR 2.97, 95% CI 1.52-5.77, P = .001) and acute blood loss anemia (OR 1.27, 95% CI 1.12-1.44, P < .0001). DISCUSSION AND CONCLUSION: Inflammatory arthritis represents a distinctly morbid risk profile compared to osteoarthritis patients with multiple increased surgical and postoperative medical complications in patients undergoing aTSA and rTSA. Surgeons should consider these potential complications and employ a multidisciplinary approach in preoperative risk stratification of IA undergoing shoulder replacement.

Anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure that has continued to evolve. Since it is a complex procedure, it carries a risk of a range of complications. To ensure optimal results, there are many important considerations to take such as the choice of graft, tunnel positioning, graft preparation, and many others. In this technical note, we elucidate our top 10 pearls to consider for a successful ACL reconstruction.
RESUMEN
Background: Upper extremity injuries account for approximately 16.9% of football injuries in the National Collegiate Athletic Association (NCAA). Purpose: To determine the epidemiology, management, and outcomes of hand/wrist injuries in collegiate football athletes so as to identify factors associated with surgical intervention and delayed return to play (RTP). Study Design: Descriptive epidemiology study. Methods: We retrospectively reviewed hand/wrist injuries that occurred within a single NCAA Division I football team from January 1, 2003, to December 31, 2020. Data analyzed included player position, college seniority, injury characteristics, injury management, surgical procedures performed, and timing of RTP. A univariate analysis was performed to identify factors associated with increased risk for surgical intervention and delayed (>21 days) RTP after hand and wrist injury in this cohort. Results: Overall, 124 patients with 168 hand/wrist injuries were identified (9.9 wrist/hand injuries per year). Sprain of the thumb metacarpophalangeal (MCP) joint ulnar collateral ligament (UCL) was the most common diagnosis (19.6%). Surgery was required in 22% of injuries, with injury of the UCL of the thumb MCP joint (8/37) being the most common indication. Injuries occurring during competitive games (odds ratio = 4.29; 95% CI, 1.2-15.9) were associated with an increased risk for surgery. Most (70%) injuries did not lead to time missed from football, whereas the remaining 30% resulted in an average of 33 ± 36 days missed. Conclusion: Over 17 athletic seasons, the annual incidence of hand and wrist injury in these NCAA Division I football players was 9.9 injuries per year, with 22% requiring surgical treatment. Injury to the UCL of the thumb MCP joint was the most common injury and indication for surgery, and 30% of injuries resulted in approximately 1 month lost. Injuries sustained in games were associated with operative management and delayed RTP.
RESUMEN
Background: Since its approval, reverse total shoulder arthroplasty (rTSA) has continued to increase in usage, with expanding indications beyond rotator cuff arthropathy. Existing literature has captured further increased utilization over the last decade through 2017. However, this data has not been updated to include a contemporary cohort of patients. This study sought to determine the trends of anatomic total shoulder arthroplasty (aTSA), rTSA, and hemiarthroplasty (HA) usage based on primary diagnosis and total number of surgeons performing each procedure annually from 2016-2020. Methods: Patients who underwent primary rTSA, aTSA, and HA from 2016-2020 were identified in the Premier Healthcare Database. Primary indication diagnoses for procedures were identified using International Classification of Diseases 10th edition codes. Temporal trends in patient and hospital demographics, primary indication, and procedure utilization were captured on an annualized basis. The number of surgeons performing each procedure annually was noted. Descriptive statistics were employed with significance set at P < .05. Results: From 2016 to 2020, 154,499 patients undergoing primary shoulder arthroplasty were identified: 48,890 aTSA, 95,808 rTSA, and 9801 HA. In 2016, rTSA comprised a slight majority (55%) of all arthroplasty cases but increased to nearly 70% of all arthroplasty cases in 2020. The absolute numbers of aTSA and HA cases decreased over time, while rTSA volume increased from 14,781 in 2016 to a high of 23,644 cases in 2019. There was a corresponding 12% increase in the number of surgeons performing rTSA across the same time period, contrasted with a 42.1% decrease in surgeons performing HA and a 14.3% decrease for aTSA. Glenohumeral osteoarthritis remains the most common indication for rTSA and aTSA, while HA is used primarily for proximal humerus fractures or hardware complications. Conclusion: The volume of primary rTSA in the United States has continued to increase from 2016 to 2020 with concurrent decreases in the number of primary aTSA and HA cases performed. Primary rTSA accounts for nearly 70% of all primary shoulder arthroplasty cases. The number of surgeons performing rTSA continues to increase, while there has been a decrease in the number of surgeons performing aTSA and HA.
RESUMEN
PURPOSE: To describe the reported return to sports (RTS) criteria following all types of shoulder arthroplasty procedures in athletes. METHODS: This scoping review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (PRISMA-ScR) as a guide. A comprehensive search was conducted in four electronic databases (Scopus, Pubmed/MEDLINE, Web of Science, and Google Scholar Advanced Search) in the English Language that reported a minimum of 1 RTS criterion in athletes after shoulder arthroplasty. The data were aggregated and summarized as frequencies, means, and standard deviations. RESULTS: Thirteen studies were included, with a total of 942 athletes with a mean age of 68.7 years. The most commonly used RTS criterion was time from surgery (range 3-6 months), reported by 7/13 (54%) of all studies, followed by restrictions on contact sports (36%). Other reported RTS criteria included no lifting/limited lifting (3/13, 23%), physician clearance based on assessment (3/13, 23%), return per patient tolerance (2/13, 15%), and upon return to full range of motion (ROM) and strength in the operated shoulder (1/13, 8%). Three studies (3/13, 23%) allowed for an unrestricted RTSpostoperatively. CONCLUSION: Thirteen studies reported one or more RTS criteria following shoulder arthroplasty, with time after surgery being the most common RTS criterion used. These results emphasise the need for interprofessional discussions and communication amongst surgeons, physical therapists, and athletic trainers to establish evidence-based RTS criteria following arthroplasty and promote a safe and effective return to sport.

Purpose: To report the outcomes of routine arthroscopic meniscectomy in National Collegiate Athletic Association (NCAA) Division I Football players. Methods: NCAA athletes who underwent arthroscopic meniscectomy over 5 years were included. Players who had incomplete data, previous knee surgery, ligamentous injury, and/or microfractures were excluded. Data collected were player position, timing of surgery, procedures performed, return to play (RTP) rate and time, and postoperative performance. Continuous variables were analyzed with Student t-tests or a one-way analysis of variance. Results: Thirty-six athletes (38 knees) who underwent arthroscopic partial meniscectomy (31 lateral, 7 medial) were included. The mean RTP time was 71 ± 39 days. The mean RTP time in athletes who underwent in-season surgery) was significantly shorter than the RTP in athletes who had off-season surgery (58 ± 41 days vs 85 ± 33 days, P < .05). The mean RTP in 29 athletes (31 knees) with lateral meniscectomy was similar to the 7 athletes (7 knees) who had medial meniscectomy (70 ± 36 vs 77 ± 56, P = .6803). The mean RTP time was similar between football players who underwent isolated lateral meniscectomy and those who had lateral meniscectomy with chondroplasty (61 ± 36 days vs 75±41 days, P = .32). Athletes played an average of 7.7 ± 4.9 games the season they returned; position category and anatomical compartment of the knee lesion had no bearing on number of games played (P = .1864 and P = .425). Conclusions: NCAA Division 1 football players who underwent arthroscopic partial meniscectomy RTP at approximately 2.5 months' postoperatively. Athletes who underwent off-season surgery had longer RTP time compared with those who underwent in-season surgery. RTP time and performance after surgery did not differ based on player position, anatomical location of the lesions, or chondroplasty at the time of meniscectomy. Level of Evidence: Level IV, therapeutic case series.
RESUMEN
BACKGROUND: Small, preliminary studies and the systematic reviews on superior capsular reconstruction (SCR) that collate data are at increased risk spin. This study's primary objective was to identify, describe, and account for the incidence of spin in systematic reviews of SCR. This study's secondary objective was to characterize the studies in which spin was identified to determine whether identifiable patterns of characteristics exist among studies with spin. METHODS: This study was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using a predetermined protocol. A search was conducted on the PubMed and Embase databases for systematic reviews and meta-analyses on SCR. Screening and data extraction were conducted independently by 2 authors. Each included study's abstract was assessed for the presence of the 15 most common types of spin, with full texts reviewed during cases of disagreement or for clarification. General data that were extracted included study title, authors, publication year, journal, level of evidence, study design, funding source, reported adherence to PRISMA guidelines, preregistration of the study protocol, and primary and secondary outcome measures. Full texts were used in the assessment of study quality per AMSTAR 2. RESULTS: We identified 53 studies during our search, of which 17 met the inclusion criteria. At least 1 form of spin was observed in all 17 studies. The most common types of spin were type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") and type 9 ("Conclusion claims the beneficial effect of the experimental treatment despite reporting bias"), both of which were observed in 11 studies (11 of 17, 65%). A statistically significant association between lower level of evidence and type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") was observed (P = .0175). A statistically significant association was also found between more recent year of publication and the spin category misleading interpretation (P = .0398), and between lower AMSTAR 2 score and type 13 ("Failure to specify the direction of the effect when it favors the control intervention") (P = .0260). No other statistical associations between other study characteristics were observed. CONCLUSION: Spin is highly prevalent in abstracts of SCR systematic reviews and meta-analyses. An association was found between the presence of spin and lower level of evidence, year of publication, and AMSTAR 2 ratings.

Background: Maxillofacial injuries account for an estimated 11% of National Collegiate Athletic Association (NCAA) sport-related injuries and occur at a rate of 0.2-1.5 injuries per 1000 athletic events/exposures. Purpose: The purpose of this study was to report the epidemiology, treatment, and outcomes of maxillofacial injuries in NCAA Division I athletes participating in 13 sports. It was hypothesized that the rate of maxillofacial injuries would be greater than previously reported in national registry studies. Study Design: Descriptive epidemiology study. Methods: A single-institution registry was utilized to retrieve the maxillofacial injuries and surgical procedures recorded over 4 athletic seasons, for the years 2015 through 2019, across 13 NCAA Division I sports. The incidence of injuries per sport was reported as the number per 1000 athlete-exposure (AE) hours. The time lost from participation and time to complete injury resolution per sport were reported as the mean and range. Results: A total of 193 maxillofacial injuries occurred over 4 seasons. The overall incidence of maxillofacial injuries was 2.06 injuries per 1000 AE hours. The injury incidence for male and female athletes was 1.92 and 2.43 injuries per 1000 AE hours, respectively. Men's basketball (8.30 injuries per 1000 AE hours) and men's water polo (8.15 injuries per 1000 AE hours) had the highest rates of all sports. Overall, 20 athletes (10.4%) required surgery. The mean time to resolution across all sports was 33.3 days (range, 0-336 days) per injury. The mean time lost across all sports was 17.1 days (range, 0-336 days) per injury. Conclusion: At a single NCAA Division I institution, maxillofacial injuries occurred at a higher rate than previously thought and could lead to significant time lost from sport participation. Basketball players were at the highest risk of this injury. Across all sports, male athletes took longer to return to sport after a maxillofacial injury compared to female athletes, but the latter required more time to fully recover. Maxillofacial injuries may require surgical treatment, and their prevention is critical.
RESUMEN
Glenohumeral arthritis in athletes or young and active individuals constitutes a challenging clinical problem, and multiple factors should be taken into consideration when deciding on nonsurgical or surgical treatment in this patient cohort. Selection of therapy should be based on clinical evidence, but the therapeutic strategy should align with patient expectations. Patient education on the nature and progression of shoulder osteoarthritis may facilitate the decision-making process regarding the selection of treatment. The orthopaedic surgeon should be knowledgeable about the nonarthroplasty options for the management of shoulder osteoarthritis in the aging athlete, with special focus on nonsurgical treatment options and shoulder arthroscopy.

Shoulder arthroplasty has become an increasingly common option for the management of glenohumeral osteoarthritis in younger, higher demand, and athletic individuals. Patients with shoulder arthritis in whom nonsurgical measures fail and who are not candidates for arthroscopic treatment may be evaluated for shoulder arthroplasty. Available options include shoulder hemiarthroplasty, with or without biologic glenoid resurfacing, total shoulder arthroplasty, and less commonly reverse total shoulder arthroplasty. The orthopaedic surgeon should be aware of the evolution and current use of the different shoulder replacement techniques in young active patients with glenohumeral osteoarthritis. In addition, it is important to review practical guidelines and issues with the implementation of those techniques when treating patients with shoulder arthritis who want to return to sport activity postoperatively.

OBJECTIVES: (1) To report the distribution of injuries per body site and time lost from participation in female NCAA Division I rowers and (2) to present an updated summary of the existing evidence regarding the analysis of injuries per body site in rowers. METHODS: Case series: The distribution of injuries per body site in female NCAA Division I rowers and the time lost from participation were retrieved from an institutional registry. Injuries per body site were reported as number of athletes with site-specific injury per total number of injured athletes. Systematic review: Based on the PRISMA guidelines for systematic reviews, three electronic databases were searched for studies reporting the epidemiology of injuries per body site in rowers and analyzed. RESULTS: Case series: One-hundred and thirty-seven injuries were recorded in 92 female rowers over 5 years. The risk of injury (number of injured athletes over total number of athletes on roaster) was 52% (92/176). Among the 92 injured athletes, 38% sustained injury to the lower back, while 23% and 16% of these athletes sustained injury to the ribs and hip-groin area, respectively. Systematic review: Ten studies were included. The level of evidence was IV and the mean MINORS score was 13.2(9-15) (fair quality). Most studies reported injuries to the lower spine (8/10,80%) whereas injuries to the ribs or other anatomic sites were reported in ≤4 (40%) studies. Significant heterogeneity of the injury reporting methodologies (injury definition; measures of injury occurrence; description of the injury site) was detected and precluded meta-analysis. CONCLUSIONS: Most injuries recorded in a single team of female NCAA Division I athletes occurred in the lower back followed by injuries to the ribs and the hip. The existing injury epidemiology literature in mostly focuses on injuries to the lower back, while injuries to other anatomic sites were less frequently analyzed. No conclusions can be made regarding the most common injuries in rowers based on the current evidence due to substantial heterogeneity of injury reported methodologies which warrants further investigation.

BACKGROUND: The slope of the tibial plateau has been proposed as a reason for failure of anterior cruciate ligament reconstruction. PURPOSE: To evaluate the interobserver reliability of measurements of tibial slope on radiographs versus magnetic resonance imaging (MRI) scans and to assess whether the modalities can be used interchangeably for this purpose. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: This retrospective study included 81 patients aged 18 to 30 years who were evaluated in a sports medicine setting for knee pain and who had lateral knee radiographs as well as knee MRI scans on file. Medial and lateral tibial plateau slope measurements were made by 3 blinded reviewers from the radiographs and MRI scans using graphic overlay software. The paired t test was used to compare measurements of the medial tibial plateau slope (MTPS) and lateral tibial plateau slope (LTPS) from radiographs and MRI scans. Intraclass correlation coefficients (ICCs) were calculated to determine intra- and interobserver reliability of measurements within each imaging modality, and Pearson correlation coefficients were calculated to determine the relationship between measurements on radiographs versus MRI scans. RESULTS: Imaging from 81 patients were included. The average MTPS was significantly larger on radiographs compared with MRI scans (8.7° ± 3.6° vs 3.7° ± 3.4°; P < .001), and the average LTPS was also significantly larger on radiographs compared with MRI scans (7.9° ± 3.4° vs 5.7° ± 3.7°; P < .001). ICC values indicated good to excellent intraobserver agreement for all imaging modalities (ICC, 0.81-0.97; P ≤ .009). The ICCs for interobserver reliability of MTPS and LTPS measurements were 0.92 and 0.85 for radiographs, 0.87 and 0.83 for MRI based off the subchondral bone, and 0.86 and 0.71 for MRI based off the cartilage, respectively (P < .001). Medium correlation was noted between radiographic and MRI measurements; Pearson correlation coefficients for radiographic versus subchondral MRI measurements were 0.30 and 0.37 for MTPS and LTPS, respectively. CONCLUSION: The average MTPS and LTPS were significantly larger on radiographs compared with MRI scans. Although tibial slope measurements using radiography and those using MRI are reliable between individuals, the measurements from radiographs and MRI scans cannot be used interchangeably, and caution should be used when interpreting and comparing studies using measurements of the tibial slope.
RESUMEN
BACKGROUND: There is a lack of consensus to guide patient return to sport (RTS) after elbow ulnar collateral ligament surgery (eUCLS). PURPOSE: To describe the reported RTS criteria after eUCLS in the athletic population. STUDY DESIGN: Scoping review; Level of evidence, 4. METHODS: This scoping review was performed by adhering to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review) guidelines. We searched 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced) and the gray literature for English-language studies that reported at least 1 RTS criterion in athletes after eUCLS. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation. RESULTS: Included were 14 studies and 1335 athletes with a mean age of 21.4 ± 1.1 years. Time from surgery (range, 6-16 months) was the most common RTS criterion used, and it was reported by all 14 of the included articles. RTS criteria reported less often were pain (3/14; 21%), successful completion of a throwing program (3/14; 21%), muscle strength of the forearm muscles (1/14; 7%), and "normal" range of motion and muscle strength of the elbow and shoulder joints on the operated upper extremity (1/14; 7%). All studies used 1 to 5 of the above RTS criteria. CONCLUSION: Only 14 studies reported 1 or more RTS criteria after eUCLS in athletes, and time was the most common RTS criterion used. Our results highlight the need for a coordinated effort among surgeons, physical therapists, and athletic trainers in order to establish evidence-based RTS criteria after eUCLS in athletes so athletes can safely to sport and prolong their athletic careers.
RESUMEN
BACKGROUND: Standardized criteria are lacking to guide patient return to sport (RTS) after rotator cuff surgery (RCS) or shoulder stabilization surgery (SSS). PURPOSE: To describe RTS criteria used after RCS and SSS in athletic populations. STUDY DESIGN: Scoping review; Level of evidence, 4. METHODS: This scoping review was based on the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review) guidelines. A total of 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced search) and the gray literature were searched for English-language studies that reported at least 1 RTS criterion in athletes after shoulder surgery. Studies were assigned to the RCS or SSS subgroup based on the primary procedure performed. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation. RESULTS: Included were 52 studies and 2706 athletes (2206 male, 500 female, with a mean age of 28.8 ± 1.8 years). The RCS group consisted of 14 studies and the SSS group consisted of 38 studies. Time from surgery was the most common RTS criterion reported overall (37/52 studies; 71%) as well as within the RCS (93%) and SSS (63%) subgroups. Muscle strength (25/52 studies; 48%) and range of motion (23/52; 44%) were used by almost half of the included articles. RTS criteria reported less often were absence of pain, successful completion of sport-specific or position-specific test, proprioception, radiographic evaluation, patient-surgeon agreement, minimum time required to participate in pain-free throwing, and satisfactory scapulothoracic mechanics. All studies used 1 to 3 of the above RTS criteria; however, the definition of each criterion differed among the included articles. CONCLUSION: Time from surgery was the most commonly reported RTS criterion after RCS or SSS in athletes, whereas muscle strength and range of motion were used by almost half of the articles. There was high heterogeneity in the definition of each RTS criterion used among the included studies, which also used different combinations of 1 to 3 RTS criteria. These results suggest the need to better define quantitative and qualitative RTS criteria in athletes undergoing rotator cuff and shoulder stabilization procedures in order to safely return athletes to sport.
RESUMEN
OBJECTIVE: To assess the diagnostic accuracy of antigen compared with reverse transcriptase (RT)-PCR testing in an asymptomatic athlete screening programme and to monitor infection in college athletes. METHODS: Quidel Sofia-2 SARS-CoV-2 Antigen Tests were performed daily before sports participation for football, basketball, wrestling and water polo from 29 September 2020 to 28 February 2021. Paired RT-PCR and antigen tests were performed at least once a week. Positive antigen tests were confirmed with RT-PCR. RESULTS: 81 175 antigen and 42 187 RT-PCR tests were performed, including 23 462 weekly paired antigen/RT-PCR screening tests in 1931 athletes. One hundred and seventy-two athletes had a positive screening RT-PCR (0.4%), of which 83 (48%) occurred on paired testing days. The sensitivity of antigen tests varied with the frequency of RT-PCR testing and prevalence of COVID-19. The sensitivity of antigen testing was 35.7% (95% CI: 17% to 60%) and specificity 99.8% (95% CI: 99.7% to 99.9%) with once-a-week RT-PCR testing after adjusting for school prevalence. Daily antigen testing was similar to RT-PCR testing two to three times a week in identifying infection. Antigen testing identified infection before the next scheduled PCR on 89 occasions and resulted in 234 days where potentially infectious athletes were isolated before they would have been isolated with RT-PCR testing alone. Two athletic-related outbreaks occurred; 86% of total infections were community acquired. CONCLUSION: Antigen testing has high specificity with a short turnaround time but is not as sensitive as RT-PCR. Daily antigen testing or RT-PCR testing two to three times a week is similar. There are benefits and drawbacks to each testing approach.
RESUMEN
For irreparable rotator cuff tears, superior capsular reconstruction (SCR) has become an option for restoring glenohumeral joint stability and reversing proximal humeral migration. Signs of irreparable rotator cuff tears include pain from subacromial impingement, muscle weakness, and pseudoparalysis. In biomechanical studies, Mihata et al. showed SCR with fascia lata graft and side-to-side suturing to remaining infraspinatus tendon restored superior stability of the shoulder joint. Adding acromioplasty decreased the subacromial contact area without altering the humeral head position, superior translation, or subacromial peak contact pressure. The same research group showed that using an 8-mm thick fascia lata graft attached at 15° to 45° of shoulder abduction optimized superior stability of the shoulder joint. Adams et al. performed SCR using a dermal allograft and found that greater glenohumeral abduction angle (60°) decreased applied deltoid force. SCR can be performed with the patient in the lateral decubitus or beach chair position. Arthroscopic exploration, debridement, and infraspinatus and supraspinatus repair attempt is completed before proceeding with SCR. To restore the superior capsule of the shoulder, the graft (fascia lata autograft, dermal allograft) can be attached to the superior glenoid medially and the rotator cuff footprint on the greater tuberosity of the humerus laterally, after debriding bone to enhance healing. SCR with side-to-side suturing to the remnant rotator cuff yields promising clinical results. Using a fascia lata autograft, Mihata et al. showed a reversal of pseudoparalysis in 93% to 96% of patients and mean active elevation, external rotation, and acromiohumeral distance on radiography all improved. Using a dermal allograft and a unique graft delivery technique, Burkhart et al. reversed pseudoparalysis in 9 of 10 patients and 70% of patients had completely intact grafts. Recommendations for rehabilitation and return to activity vary, but adequate time for graft healing is recommended.

BACKGROUND: Beach volleyball officially became a National Collegiate Athletic Association (NCAA) Division I sport in 2015-2016. Few studies have examined the epidemiology of injuries in indoor versus beach volleyball in NCAA Division I athletes. PURPOSE: To compare the epidemiology of injuries and time lost from participation between female NCAA Division I athletes who participate in indoor versus beach volleyball. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Injury surveillance data (2003-2020) were obtained using an institutional database for all NCAA Division I women's beach or indoor volleyball athletes. The total injury rate was expressed per 1000 hours played. The injury rate per body site was calculated by dividing the number of injuries in each body region by the total number of injuries. The frequency of injury per body site was also expressed as number of injuries per 1000 hours of practice or number of injuries per 1000 hours of game. The injury rate (total and per body site) and time lost from participation were compared between indoor and beach volleyball athletes. RESULTS: Participants were 161 female NCAA Division I volleyball athletes (53 beach volleyball and 108 indoor volleyball athletes). In total, 974 injuries were recorded: 170 in beach volleyball and 804 in indoor volleyball. The injury rates for beach versus indoor volleyball were 1.8 versus 5.3 injuries per 1000 hours played (P < .0001). Indoor volleyball athletes had significantly higher injury rates compared with beach volleyball players for concussion (7.5% vs 6.5%; P < .0001) and knee injury (16.7% vs 7.6%; P = .0004); however, the rate of abdominal muscle injury was significantly higher in beach versus indoor volleyball (11.8% vs 4.7%; P = .0008). Time lost from sport participation was significantly longer in beach versus indoor volleyball for knee (24 vs 11 days; P = .047), low back (25 vs 17 days; P = .0009), and shoulder (52 vs 28 days; P = .001) injuries. CONCLUSION: Based on this study, injury was more likely to occur in indoor compared with beach volleyball. Sport-related concussion and knee injuries were more common in indoor volleyball, but the rate of abdominal muscle injury was higher in beach volleyball. Beach volleyball players needed longer time to recover after injuries to the knee, low back, and shoulder.
RESUMEN
BACKGROUND: Monitoring vitamin D levels in athletes and determining their response to supplementation in cases of deficiency is thought to be necessary to modulate the risks associated with vitamin D deficiency. HYPOTHESIS/PURPOSE: To report the results of a 5-year-long surveillance program of vitamin D in the serum of football players on a National Collegiate Athletic Association (NCAA) Division I team and to examine whether factors including age, body mass index (BMI), race, position played, and supplement type would affect the response to 12-month oral vitamin D replacement therapy in athletes with deficiency. We hypothesized that yearly measurements would decrease the proportion of athletes with vitamin D insufficiency over the years and that the aforementioned factors would affect the response to the supplementation therapy. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We measured serum 25(OH)D levels (25-hydroxyvitamin D) in 272 NCAA Division I football players from our institution annually between 2012 and 2017. Athletes with insufficient vitamin D levels (<32 ng/mL) received supplementation with vitamin D3 alone or combined vitamin D3/D2. The percentage of insufficient cases between the first 2 years and last 2 years of the program was compared, and yearly team averages of vitamin D levels were calculated. Associations between player parameters (age, BMI, race, team position, supplement type) and failed supplementation were evaluated. RESULTS: The prevalence of vitamin D insufficiency decreased significantly during the study period, from 55.5% in 2012-2013 to 30.7% in 2016-2017 (P = .033). The mean 25(OH)D level in 2012 was 36.3 ng/mL, and this increased to 40.5 ng/mL in 2017 (P < .001); however, this increase was not steady over the study period. Non-Hispanic athletes and quarterbacks had the highest average 25(OH)D levels, and Black players and running backs had the lowest overall levels. There were no significant differences in age, BMI, race, or playing position between athletes with and without failed vitamin D supplementation. Athletes receiving vitamin D3 alone had a more successful rate of conversion (48.15%) than those receiving combined vitamin D3/D2 (22.22%; P = .034). CONCLUSION: To decrease the prevalence of vitamin D deficiency in football players, serum vitamin D measurements should be performed at least once a year, and oral supplementation therapy should be provided in cases of deficiency. Black players might be at increased risk of vitamin D insufficiency. Oral vitamin D3 may be more effective in restoring vitamin D levels than combined vitamin D3/D2 therapy.
